• Notes

• This new instrument, which has some features of the previous DM 2020, but a longer scale and built-in ratiometer facilities.
  Accuracy is up to 0.0025 percent full scale ±0.01 percent of reading.
  It covers from 0 to 2 kV in five ranges, with a sensitivity on the lowest range being 10 µV.
  The input impedance is greater than 25,000 Ω on the two lowest ranges, and 10 MΩ on the higher ranges.
  The input can be isolated from earth.

  All characteristics are much more clearly described in the original attached article.
